Default Re: Moore's Law original issue! OMG!

Where's JoeP? New South Wales has made a single atom transistor. I heard an interview with one of the researchers on NPR, and this may be scalable. She said that only a few hundred of these transistors would be needed for computing, but I'm not sure why that would be.

Physicists create working transistor consisting of a single atom

Quote:
Science Daily - In a remarkable feat of micro-engineering, an international team of researchers, including physicists at the University of New South Wales in Australia, have created a working transistor consisting of a single atom placed precisely in a silicon crystal.
She mentioned that the transistor would switch between energy states rather than voltage levels to represent digital values. :girlscientist: Here is the link to the NPR interview, it's p. interesting. Reaching For The Limits of Tiny Transistors : NPR

I guess in the world of quantum computing, you are actually using a completely different way of doing the computing. So you're using what's called parallelism, quantum parallelism. So instead of doing calculations in the classical world one after the other, albeit very fast, you actually do these calculations in parallel.

And there are certain kinds of calculations where if you can do things in parallel, you can get a predicted exponential speed-up in the computation. And I guess that's one of the reasons why quantum computation is quite an exciting field at the moment. If you can actually realize them then there are certain tasks that you can do which would be much faster than you can do with classical computers.
ES?
